APPLICATIONS
Tubular heaters can be
used in almost any application. They can be clamped to metal surfaces or
inserted in machined grooves for conductive heat transfer. Or use a formed
Tubular heater to provide consistent heat in any type of special application.
Typical applications include Ovens, Duct heating, Tank heating, Hopper heating,
Platen & dies, Castable heaters etc.
SPECIFICATIONS
TUBE SHEATH MATERIALS
Different sheath
materials are available for different applications. Options include Copper, SS
304, SS 316, SS 321, Incoloy.Tolerances: Resistance +10% – 5%, Wattage + 5%
–10%, Length +/– 3%.
TUBE DIAMETERS
Tubular heating elements
are available in the following diameters.
Tube dia : 8 mm, 11 mm,
14 mm, 17 mm, 19 mm.
Tubular heaters lengths
can extend upto 5.8 meter +
Maximum Sheath Watt
Density: 30 w / in2
NOTE: Cold zone at each
end: 1-1/2” min.
MOUNTINGS
Variety of mountings are
available to suit the application area. Tubular heaters can be brazed or welded
to different sizes of threaded flanges, plate flanges, nipples, bolts.
FINNED TUBULAR HEATERS
Tubular heaters of any
diameter can be finned with steel or stainless steel finn material to increase
the surface area. Finns can be spiral in shape or punched to suit the
application. Designed for rapid uniform heat transfer in air heating ducts.
Also used in blower type comfort heating units, recirculating ovens and other
industrial processing equipment & processes requiring heated air.
TYPICAL BEND FORMATIONS
The following are a
few, but by no means the only, ways tubular heaters can be formed. For other
shapes, please provide us with dimensional details,
drawings or samples.
